Benang extended two drainage culvert barrels under a live rail corridor at Grass Valley for Arc Infrastructure, completing investigation, design validation, and earthworks with critical lifts under strict rail safety operations.

Client: Arc Infrastructure
Sector: Land Development
Services: Water, Civil
Location: Grass Valley, WA
Dates: March to April 2020

Challenge
The culverts sit in a live rail environment, so every lift and excavation had to run under critical lifting procedures and strict rail safety operations.
Approach
Benang completed the investigation and design validation, then carried out the earthworks to extend two drainage culvert barrels, executing critical lifts inside the live rail corridor for batter surface water management and erosion control.
Outcome
The extension was completed with 30 per cent Aboriginal participation, zero lost time injuries, and zero environmental incidents.
